Profile Service Spinlock Problem Causes 100% CPU Consumption
This article was previously published under Q307409
Dllhost.exe or Inetinfo.exe may show 100% CPU consumption
either in Task Manager or Performance Monitor. Further investigation using
Autodump+ shows that MSCSUps is engaged in multiple spinlocks that are spread
across multiple threads. Performing an IISRESET temporarily remedies the
symptoms.
A spinlock resource is not released reliably, which results
in a deadlock condition. The 100% consumption state is caused by the MSCSUps
component continuously checking to see if a lock has been cleared.
To work around this problem, restart the Web service. Note
that this results in lost user sessions.
To
resolve this problem, obtain the latest service pack for Microsoft Commerce
Server 2000. For additional information, click the following article number to

Community Feedback System
Very often, it takes hours to solve a problem. Very often, you've looked high
and low, and have tried a lot of solutions. When you finally found it, chances
are, it was because someone else helped you. Here's your chance to give back.
Use our community feedback tool to let others know what worked for you and what
didn't.
Please also understand that the community feedback system is not warranted to be
correct, it's simply a system that we've built to let people try and help each
other. If something in a feedback response doesn't make sense to you, or you're
not comfortable making changes that the feedback talks about (like registry
edits), please consult a professional.
Thank you for using kbAlertz.com Feedback System.
